The top of the keyboard isn't actually fabric, it's more like a textured vinyl. The bottom is felt (odd choice, dirt magnet, can't clean it) You could actually use a mild cleaner on the top part though. That being said, I was never able to get the dirt fully out of the blue keyboard, wound up getting a black one instead. I think about as light as I'd go now is the new Best Buy blue one.Thoughts?
It was a poor choice of textile -- common sense sort of dictates you wouldn't cover a laptop with felt -- yet that's exactly what Microsoft did by making the back of the keyboard felt. Someone suggested at another site that products designed to clean felt pool tables might work -- that seems kind of involved...duh, no luck
